Woodruff Key

Woodruff keys are mechanical fasteners used to secure rotating machine parts, such as gears or pulleys, to a shaft. They are commonly used in automotive, industrial, and machinery applications.

Woodruff keys have a unique half-moon shape, with a rounded top and a flat bottom. The keyway on the shaft is also shaped to match the key, creating a secure and precise fit. The key prevents the rotating part from sliding or rotating on the shaft, ensuring proper alignment and transmission of power.

Woodruff keys are typically made of steel and are available in various sizes to accommodate different shaft diameters and keyway dimensions. They are often used in conjunction with a keyseat cutter to create the keyway on the shaft.

In the supply class Nails, Machine Keys, and Pins, Woodruff keys are categorized as machine keys. They are commonly found in the Hardware and Abrasives supply group, which includes various hardware components and abrasive materials used in construction, manufacturing, and maintenance applications.
